Friction stir processing (FSP) is a typical process for refinement changes of microstructure, enhance material's mechanical properties, and fabricating surface layer composites. The cast A356 surface composites were fabricated via Friction Stir Processing (FSP) and the enhancement of it’s metallurgical and mechanical properties are studied and conveyed in this research study. The three combinations of test samples of FSP'ed cast A356 alloy, FSP'ed cast A356 FSP with tungsten nanoparticle addition (5 and 10 vol%) were considered to fabrication under fixed parametric conditions like tool rotational speed of 1000 rpm, a load acting 9 kN,./ tool travel speed of 20 mm min−1 through four number of tool travel passes respectively. Obtained FSP'ed samples were exposed to microstructural, tensile strength tests and fracture surface morphology analysis were carried out to record the responses.

The prime purpose of this investigation is to determine the consequence of T6 heat treatment on the mechanical characteristics of squeezed A356 alloy. A356 alloy is one of the most promising aluminium alloys owing to its excellence in casting, conflict to corrosion, and high strength-to-weight ratio. Processing methods and types of reinforcements used are the major driving force towards the change in the properties of the aluminium alloys. However, heat treatment also employed in order to show strong static mechanical properties and enhancing the metallurgical characteristics of the matrix material. The primary objective of this investigation is to compare the mechanical properties of squeezed pure A356 alloy with samples that have undergone T6 heat treatment and artificial aging. Squeeze casting technique is employed in this research work to get the near net shaped components with fine structure, great surface finish, insignificant porosity and shrinkage.

The primary goal of this analysis is to investigate the effect of heat treatment processes on the tribological properties of squeeze cast A356 Alloy. Because of its excellent mechanical and tribological properties, the proposed A356 alloy has a wide variety of uses in the automotive industry. Squeeze casting is a cost-effective and promising method of producing aluminium alloy with better properties and a pore-free construction. Furthermore, the properties can be improved using post-processing techniques such as heat treatment, and residual stresses are eliminated as a part of the heat treatment procedure. The aim of this study is to look into the impact of post-processing methods on the tribological properties of squeeze cast A356 alloy. The prepared samples' wear resistance and friction characteristics were measured using a pin-on-disc tribometer test setup under dry sliding conditions with an applied load of 10, 20, 30, and 40N with a steady sliding velocity of 3 m/s.

his research work aims to investigate the effect of flyash and MoS2 lubricant particles on the tribological properties of AlSi7Mg alloy fabricated through stir cum squeeze casting process. AlSi7Mg alloy is a supreme favourable industrial aluminium alloy owing to its exceptional casting ability, corrosion resistance and good strength to weight ratio. Stir casting is an effective and capable processing route for making aluminum composites with enhanced properties. Additionally, to achieve enhanced properties and a pore-free structure, stir cum squeeze casting processing was used to fabricate aluminium matrix composites. In the experimental investigation, AlSi7Mg alloy was reinforced with 0, 5, 10wt% flyash and 3wt% MoS2 and processed by stir cum squeeze casting method.
